Astronomers have evidence for black holes in nearly every galaxy in the universe

Although¹ no black hole is close enough to Earth to pull the planet into its depths, there are so many black holes in the universe that counting them is impossible. Nearly every galaxy — our own Milky Way as well as the 100 billion or² so other galaxies visible from Earth — shows signs of a black hole.

Of the billions of stars in the Milky Way, about one in every thousand new stars is massive enough to become a black hole. Our sun isn’t. But³ a star 25 times heavier is. Stellar-mass black holes result from the death of these stars, and⁴ can exist anywhere in the galaxy.

Supermassive black holes — a million to a billion times more massive than our sun — exist only in the center of a galaxy. At the center of the Milky Way, 26,000 light-years from Earth, scientists are hoping to make an image of Sagittarius A*, which is believed to be our own supermassive black hole, with the mass of four million suns. How supermassive black holes form is still a mystery.
